Abstract: Anti-reflective (AR) coatings and methods for applying AR coatings to substrates, such as optical lenses. The coating may include a polyurethane base layer and a fluoropolymer top layer. The base layer may protect the underlying substrate, promote adhesion between the top layer and the underlying substrate, and achieve index-matching with the underlying substrate. The method may involve an inexpensive and efficient solution coating process.

Abstract: A polarizing plate, a liquid crystal display device having the polarizing plate and a method of fabricating the polarizing plate are characterized by forming an anti-glare/reflection layer, which is formed into a single layer through one coating process using a phase separation resulting from a weight difference between polymer beads and air bubbles. This may result in ensuring cost competitiveness.

Abstract: The present invention provides a method of producing hollow particles for reducing light scattering in an antireflection coating. This method includes synthesizing core-shell particles including a core containing an organic compound as a major component and a shell containing an inorganic-based compound as a major component in an aqueous medium, dispersing the core-shell particles in an organic solvent, and preparing hollow particles by heating the core-shell particles dispersed in the organic solvent to remove the core therefrom.
